Eron and Evalia are both wearing enchanted armors and swords. Aside from that, their shoes and bracers were also decent artifacts that could provide a good boost to their defense.
Each of them is wearing a total of six Artifacts… It's a bit concerning if it's done by a newbie since having many Artifacts also means having many sources of exhaustion. After all, all Artifacts require an Aura to function effectively.
Nevertheless, as long as the two know how to balance their usage, there should be nothing to worry about.
As for Melody, she only has a total of four Artifacts including the Shaman Gloves.
Nevertheless, the three of them are all Rank-B Artifacts so they were more reliable. It was her Spear, Bracelet, and Armor.
